Tottenham boss Andre Villas-Boas has come under fire from a brain injury charity for his ‘irresponsible and cavalier attitude’ towards Hugo Lloris’ health during the stalemate at Everton.

The French goalkeeper was momentarily knocked unconscious after Romelu Lukaku’s knee clattered off his head in a race for the ball, but Lloris remained on the pitch after lengthy treatment.

Villas-Boas revealed he made the call to keep Lloris on the field due to the positive signals he was giving the physio, but brain injury charity Headway claim the manager risked the long-term health of his goalkeeper with his decision.

It told the BBC: ‘When a player – or any individual – suffers a blow to the head that is severe enough for them to lose consciousness, it is vital they urgently seek appropriate medical attention.

‘A physio or doctor treating a player on the pitch simply cannot accurately gauge the severity of the damage caused to the player’s brain in such a setting as there may be delayed presentation of symptoms.

‘By continuing to play, the player may have caused greater damage to his brain. He should have been removed from the game immediately and taken to hospital for thorough tests and observation.’
